According to the classification of oil grooves, grooved jewel bearings can be divided into spherical, conical, single-sided double spherical, double- sided single spherical and other types. It plays a supporting role in the spherical surface of electrical measuring instruments, thermal measuring instruments,hydraulic measuring instruments, single-phase and three-phase electroplating meters, aviation and marine instruments, meteorological instruments and other instrument moving systems.
